LAMP-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 659,247. dated October 9, 1900- Application filed August 6, 1900- Serial No. 26,070. \N0 mOdel-J To all whom it may concern,.- the cap is turned down. From the opposite Be it known that I, WILLIAMy C. MILLER, a sides of the wick-tube 4 adjacent to its upper citizen of the United States, residing at Linend extend a pairof horizontal alined pintles coln, in the county of Lancaster and State of 7 and 8, constituting journals for a pair of 55 5 Nebraska, have invented a new and useful pivoted hood-sections 9 and 10. These hood- Lamp-Extinguisher, of which the following is sections, as more clearly shown in Fig. 3, are a specification. y of approximate U shape in cross-section to This invention relates to improvements in envelop the opposite edges of the tube 4 lamp-extinguishers, one object being to prowhen turned down and to constitute a cover 6o io duce a simple, inexpensive, and elicient deor hood for the wick when swung upwardly vice by means of which the extinguishment into an abutting position, as shown in Fig. 2 of a lamp may be effected manually or autoof the drawings. matically to obviate the necessity for blow- At one side of the wick-tube the hood-secing into the lamp-chimney and to preclude tions are provided with oppositely-extending 65 the possibility of a conagration due to the arms 1l and 12, the ends of which are overtilting or overturning of the lamp.` lapped and pierced by the pintle 8. It will A further object of theinvention is to renbe noted that when the hood-sections are der the action of a pair of pivoted hood-secswung above the wick their edges are detions or jaws more certain by pivoting the signed to abut into coincidentrelation for the 7o 2o hood-sections upon a common pintle and by purpose of effecting the complete exclusion extending an operating-arm from each hood of ai'r from the wick. The arms 11 and 12 beyond its pintle for attachment to the ends are therefore offset from the contiguous walls of a flexible loop, to which is connected a of the`hood-sections, the arm 11 beingsecured flexible piece passed through the globe-base to the inner face of one wall and the arm l2 75 and provided with a weight designed by its to the outer face of the other, as shown in intentional or accidental displacement from Fig. 3. At the opposite side of the wick-tube a rest or support to swing the hood-sections the hood-section 10 is provided with a short above the weight for the purpose of extinbearing-arm 13, mounted upon the inner face guishing the iiame. of the adjacent wall of the member and fixed 8o 3o To the accomplishment of these objects the to a bearing-sleeve 14, having a bearing upon invention consist-sin the construction and the pintle 7, from the outer end of which arrangement of parts hereinafter described, sleeve is extended an operating-lever 15, disillustrat-ed in the accpmpanying drawings, posed atan obtuse angle to the inner edge 16 and defined in the appended cI'aims. of the section 10. A bearing-arm 17, similar 85 In said drawings, Figure 1 is a perspective to the arm 13, is extended from the section 9, view of my device applied to a lamp of ordibut is oset upon the outer face of the wall nary construction, the hood-sections being and has a bearing upon the sleeve 14, the exthrown back. Fig. 2 is an elevation of the tremity of the arm 17 being extended beyond subject-matter of Fig. 1, showing, the hoodthe sleeve to form an operating-lever 18. The 9o 4o sections closed by the gravitation of the angular relation of' each of the operating-leweight. Fig. 3 is a sectional View on the line vers 15 and 18 with respect to the inner and 3 3 of Fig. 1, and Fig. 4 is a detail perspective outer edges of the hood-sections is such that View of one of the hood-sections. in either the elevated or depressed position Referring to the numerals of reference cmof said sections the levers will be related at 95 ployed to designate corresponding parts an angle of approximately forty-five degrees,

throughout the views, 1 indicates a fragment their locations being above or below the horiof a lamp-body; 2, the cylindrical neck of zontal, as the case may be. For the purpose the lamp-top; 3, Vthe usual foraminous globe of swinging the arms 15 and 18 to effect the support or base; 4, the Wick-tube, and 5 the elevation of the hood-sections and the exroo 5o usual hinged cap,provided with a diametrical tinguishment of the flame I provide a weight slot 6, positioned above the wick-tube when 19, secured to the lower end of the flexible piece or chain '20, pendent from a flexible loop 2l, having its ends secured to the extremities of the levers and constituting, in effect, a pair of divergent branches of the piece 20, which I will therefore designate in the claims as a branched flexible piece, having direct connection with the levers. The weight-supporting piece 2O extends downwardly through a tubular guide 22, piercing the globe-base 3, and the weight, which is preferably of spherical form, is normally supported upon a rest or seat 23, located below the base 3and preferably formed by bending a strand of wire around the neck 2 of the lain ptop and by deflecting the strand to form a somewhat more than semicircular projection defining the seat 23.

Assuming the parts to be positioned as shown in Fig. l, it will be seen that the removal of the spherical weight 19 from the seat 23, either by design or by the accidental tilting or overturning of the lamp, will cause said weight to exert a downward pull upon the flexible piece 2O to swing the operatinglevers from positions above the horizontal to corresponding positions below the horizon tal, as shown in Fig. 2 of the drawings, the effect of which will be to swing the hood-sections 9 and l0 to abutting positions above the wick, effecting the exclusion of air from the flame and causing its instant extinguishment.

From the foregoing it will be observed that I have produced a simple and efcient lampextinguishing device comprehending a pair of pivoted hood-sections arranged normally to gravitate to positions at opposite sides of the wick tube and to be swung above the wick through the medium of a directly-connected flexible piece carrying an actuatingweight, the operation of the sections being effected without the necessity for the employment of sliding connections or other motiontransmifting devices productive of considerable friction; but while the present embodiment of my invention appears at this time to be preferable I desire to reserve the right to eect such changes, modifications, and variations as may be properly comprehended within the spirit of the invention.

What I claim isl. A lamp-extinguisher comprising a pair of pivoted hood-sections designed to close above a wick-tube, operating-levers extending in opposite directions from the pivot of the sections, a flexible piece connected directly to both of the levers, and a weight connected to the flexible piece to exert a direct pull upon the levers t0 effect the closing of the hood-sections.

2. A lamp-extinguisher comprising a pair of pivoted hood-sections designed to close over a Wick-tube, a pair of operating-levers extendingin opposite directions from the sections and disposed in obtuse angular relation to the abutting faces thereof to locate them in upwardly-divergent positions when the sections are depressed, a branched flexible piece connected to the outer ends of said levers and a weight connected to the lower end of said piece and designed to exert a direct downward pull to swing the levers downwardly from positions above the horizontal.

3. The combination with a lamp-top comprisinga neck, a globe-supporting base and a wick-tube, of a pair of pivoted hood-sections designed t0 close over the wick tube, operatinglevers extended from said sections, a branched flexible piece having its branches connected to the levers, a weight suspended by the piece, a seat for said weight, and a supporting device for the seat, encircling the neck of the lamp-top.

4. The combination with a lamp-top comprising a neck, a globe-supporting base, and a Wick-tube, of a'pair of pivoted hood sections designed to close over the wick-tube, operating-levers extended from said sections, a flexible piece directly connected to the levers and passed through the globesupporting base, a Weight suspended by the flexible piece, and a seat for said weight located below the base.

In testimony that I claim the foregoing as my own l have hereto aixed my signature in the presence of two witnesses.

WILLIAM C. MILLER.
